Safety Precautions

All safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this product.

DANGER

Strictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life.

1. Always disconnect the product from the power source and peripheral devices when servicing the product or performing maintenance.

2. When performing works described in this manual, do not connect to a power source until instructed to do so. Connecting to a power source causes high voltage in the power supply unit and some electronic components even if the product power switch is off. If you need to perform the work with the power cable connected to a power source, use extreme caution to avoid electrical shock.

WARNING

Strictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.

1. Always wear protective goggles for disassembly and reassembly to protect your eyes from ink in working. If any ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.

2. When using compressed air products; such as air duster, fo r cleaning during repair and maintenance, the use of such products containing flammable gas is prohibited.

PRECAUTIONS

Strictly observe the following cautions. Failure to comply may lead to personal injury or damage of the product.

1. Repairs on Epson product should be performed only by an Epson certified repair technician.

2. No work should be performed on this product by persons unfamiliar with basic safety knowledge required for electrician.

3. The power rating of this product is indicated on the serial number/rating plate. Never connect this product to the power source whose voltages is different from the rated voltage.

4. Replace malfunctioning components only with those components provided or approved by Epson; introduction of second-source ICs or other non-approved components may damage the product and void any applicable Epson warranty.

5. The capacitors on the Main Board may be electrically charge right after the power turns off or after driving motors which generates counter electromotive force such as when rotating the PF Roller or when moving the CR Unit. There is a risk to damage the Main Board if the Head FFC is short-circuited with the capacitors on the Main Board electrically charged, therefore, after the power turns off or after motors are driven, leave the printer untouched for approximately 30 seconds to discharge the capacitors before starting disassembly/ reassembly.

6. To prevent the circuit boards from short-circuiting, be careful about the following when handing FFC or cables.

When handling FFC, take care not to let the terminal section of FFC touch metal parts.

  When connecting cables/FFC to the connectors on circuit board, connect them straight to the connectors to avoid

slant insertion.

7. In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static wrist straps, when accessing internal components.

8. Do not tilt this product immediately after initial ink charge, especially after performing the ink charge several times. Doing so may cause ink to leak from the product because it may take some time for the waste ink pads to completely absorb ink wasted due to the ink charge.

9. Never touch the ink or wasted ink with bare hands. If ink comes into contact with your skin, wash it off with soap and water immediately. If you have a skin irritation, consult a doctor immediately.

10. When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal parts with sharp edges.

11. Use only recommended tools for disassembling, assembling or adjusting the printer.

12. Observe the specified torque when tightening screws.

Nozzle plate of the printhead

  CR Scale  PF Scale  ASF Scale  Coated surface of the PF Roller  Gears  Rollers  LCD  Scanner Sensor  Exterior parts

14. Never use oil or grease other than those specified in this manual. Use of different types of oil or grease may damage the component or give bad influence on the printer function.

15. Apply the specified amount of grease described in this manua l .

16. Make the specified adjustments when you disassemble the printer.

17. When cleaning this product, follow the procedure described in this manual.

18. When transporting this product after filling the ink in the printhead, pack the printer without removing the ink cartridges in order to prevent the printhead from drying out.

19. Make sure to install antivirus software in the computers used for the service support activities.

20. Keep the virus pattern file of antivirus software up-to-date.

21. When disassembling/reassembling this product, if you find adhesive power of the double-sided tape which secure the parts or FFC is not enough, replace the tape with new one and attach it correctly to the specified points where the parts or FFC should be secured.

22. Unless otherwise specified in this manual, the labels attached on the returned product should be transferred to the corresponding attachment positions on the new one referring to the labels on the returned product.

2.2 Disassembly/Reassembly Procedures

2.2.1 Caution when Replacing the Printhead/Ink Supply Unit

For stable ink supply, this product employs a mechanism where the ink in the ink path is pressurized even the power is off. Therefore, if the joint section of the printhead and the Ink Supply Unit is simply disconnected, the ink in the ink tube will spill over.

Figure 2-1. Joint Section of the Printhead and Ink Supply Unit

To prevent this from happening, before separating the Printhead and Ink Supply Unit to replace the Printhead or the Ink Supply Unit, make sure to release the pressure inside the ink path using the Adjustment Program. The following explains the procedure.

 This is not necessary when replacing the Printhead and Ink Supply Unit together.  Approximately two minutes are required to release the applied pressure.  The ink in the ink path is pressurized in the power-off sequence again, therefore, make

sure not to turn the power off by the power button after the applied pressure is released.

 Tools

 Ink Cartridges Do not use user’s ink cartridges since the ink in the ink cartridges is consumed when releasing the

pressure. Prepare ink cartridges supplied as consumables for this procedure. (Hereafter, an ink cartridge for this purpose is called as an “ink cartridge (for service use)”.

 Maintenance box

Do not use user’s maintenance box since the ink the ink path flows to the maintenance box when releasing the pressure. Prepare maintenance box supplied as a consumable for this procedure. (Hereafter, a maintenance box for this purpose is called as a “maintenance box (for service use)”.

 Make sure to use the same service Ink cartridge and Maintenance Box from “ Ink

Pressure release” to “Initial Charge”.

 Before performing Ink Pressure Release, confirm the proportion of remaining capacity

of the Maintenance Box is 30% or more.

 Procedure

1. Remove the ink cartridges and maintenance box in the returned unit, and install the ink cartridges and maintenance box

(for service use).

(for service use)

2. Connect the printer and the PC installed the Adjustment Program with the USB cable, and turn the power on.

3. Start the Adjustment Program, and select the “Ink Pressure Release” from the menu.

4. Click “Execute” in the displayed screen to release the applied pressure.

5. When the completion message appears, unplug the computer power cable.

Afterward, remove the parts referring to "2.2.2 Parts/Units Need to be Removed in Advance (p32)" and replace them referring to "2.2.3 Disassembly Flowchart (p33)".

Ink Supply Unit

Print head

 When separating the Printhead and the Ink Supply Unit, make sure to perform "3.2.5

Ink Leak Check (p74)" to check if ink is leaking.

 After disconnecting the Printhead and the Ink Supply Unit, ink may spill over even if the

pressure is released. Therefore, be careful not to contaminate the surroundings.

 Make sure that the buffer is being deflated before the print head is removed, as shown

below. If the buffer is inflated, make sure to perform the “Ink pressure release” again, because the ink is not discharged condition.

Figure 2-2. The buffer condition before and after performing the ink pressure release

 Printer cannot perform Ink Pressure Release when Printer is error condition.

Therefore, when Printer cannot perform Ink Press ure Release by fatal error, Perform the repair operation by the "Repair operation of Print Head and Ink Supply Unit (When

the Printer cannot perform the Ink Pressure Release by fatal error) (p31)".

2.2.3 Disassembly Flowchart

This section describes procedures for disassembling the parts/units in a flowchart format. For some parts/units, detailed procedures or precautions are provided (accordingly indicated by icons and cell's color). Refer to the explanations in the example chart below and perform an appropriate disassembling and assembling procedure. (See "2.3 Detailed Disassembly/Reassembly Procedure for each Part/Unit (p41)" .) For routing cables, see "2.4 Routing FFCs/Cables (p49)".

2.2.3.1 Parts/Units whose Configuration is Different between Models in the Flowchart

The models describe in this manual employ the same printer mechanism but they have different printing related functions and structures. Therefore, the parts/units vary and the shape of them differs even they have the same parts name.

In the flowchart in this section, the parts are in two colors: black for the common parts or units, and blue for the parts or units which differ between models. For the parts or units which differ between models, confirm the composition of the parts for the printer whose disassembly procedure you want to check, and then see the disassembly flowchart.

3.1 Required Adjustments

The table from the following page lists the required adjustments depending upon the parts being repaired or

replaced. Find the part(s) you removed or replaced, and check which adjustment(s) must be carried out.

 After all required adjustments are complete, use the “Final check pattern print” function

to print all adjustment patterns for final check. If you find a problem with the printout patterns, carry out the adjustment again.

 When replacing the Main Board and the Printer Mechanism (Frame Base Assy) at the

same time, the adjustment should be made after performing the initial setting.

 In this manual, the product name is abbreviated to such as “WP-5620 series”, however,

the last digit of the actual name may differ. Identify your product with the first three digits and refer to the appropriate sections in this manual.

 The table items and marks used in the “Required Adjustment List” provided on the

following pages have the following meanings.

• “O” indicates that the adjustment must be carried out.

• “---” indicates that the adjustment is not required.

• The “Mechanism Adjustment” should be performed just after reinstalling or reassembling the part or unit. (See "Table 3-1 Required Adjustment List (Mechanism

adjustment) (p55)".)

• The “Adjustments using the Adjustment Program” need to be performed after reassembling the printer completely. (See "Table 3-2 Required Adjustment List

(Adjustment using the Adjustment Program) (1/2) (p57)", "Table 3-3 Required Adjustment List (Adjustment using the Adjustment Program) (2/2) (p59)".)

 If you have removed or replaced multiple parts, make sure to check the required

adjustments for the all parts. And when multiple adjustments must be carried out, be sure to carry them out in the order given in the “Priority” row.

Do not touch or press the regulator located under the regulator protection plate of the Ink Leak Measurement Jig.

 The Ink Leak Measurement Jig applies pressure by sending air using a syringe into the

ink path, and detects the variation of pressure in the ink path between the self-sealing valve in the Printhead and the ink supply holes of the ink cartridges to check the presence of ink leakage. If air leak occurs in the Ink Leak Measurement Jig, the leak check itself cannot be done. Therefore, before performing the leak check, perform "Ink

Leakage Inspection Condition (p76)" without inserting the Ink Leak Check Cartridge to

the printer to test air leak from the Ink Leak Measurement Jig itself. (If the Ink Leak Check Cartridge is not loaded to the printer, the valve in the cartridge is shut. Therefore, the air leak check from the Ink Leak Measurement Jig itself becomes possible.)

 The ink leak check should be done with the ink tubes secured with the tube clamps and

the CR Cover attached after the joint section of the Printhead and the Ink Supply Unit has been secured. (See "Ink Supply Unit (p45)".)

Checking procedure

 Make sure to pressurize the pressure of the specified value (48±2Kpa), and do not

pressurize the pressure of more than specified value.

 If you pressurize the pressure of the more than the specified value, it can not lower the

pressure by pulling the syringe. (Because, the ink supply jig has valve to prevent back flow of the ink. If you lower the pressure by pulling the syringe, the valve is closed and can not perform the reliable test.)

 If you pressurized the pressure of the more than the specified value, reassemble the

connection parts of printhead and the Ink Supply Jig to lower the pressure of the Ink Tube of the Ink Supply Unit.

1. Checking procedure of the Leak Check Measurement

1. Turn each valve of the Ink Leak Measurement Jig as follows:



Valve A: Open

 Valve B: Open  Valve C: Open

2. Connect the Ink Leak Check Cartridge to the Ink Leak Measurement Jig.

Epson WF-M5690/M5190 series Revision B

4.1 Overview

This section provides information to maintain the printer in its optimum condition.

4.1.1 Cleaning

Except for the printhead, there are no other mechanical parts or units that require periodic cleaning. However, if need arises, clean the component observing the following instructions.

 Instructions for cleaning



Exterior parts such as housing Wipe dirt off with a soft clean cloth moistened with water. For glossy or transparent parts, use of unwoven cloth is recommended to avoid scratching those parts.

 Inside of the printer

Remove paper dust with a vacuum cleaner.

 Rubber or plastic rollers such as an LD roller/Pickup Roller used to feed paper

If paper dust adhered to the rollers decreases the frictional force of the rollers and the rollers cannot properly feed paper, wipe off the paper dust with a soft cloth moistened with diluted alcohol.

 Instructions for cleaning ink stains

Wipe the stains off with a cloth wrung out of diluted alcohol.

 Do not use alcohol for cleaning the transparent parts. Doing so may cause them to get

cloudy.

 When wiping paper dust off the LD roller/Pickup Roller, be careful not to rub against the

surface asperity.

 To minimize the effect on the parts, use diluted alcohol such as 70% diluted ether.  After using alcohol for cleaning, make sure to wipe the part off with a soft dry dust-free

cloth to remove alcohol traces fully.

4.1.2 Lubrication

The type and amount of the grease used to lubricate the printer parts are determined based on the results of the internal evaluations. Therefore, refer to "4.2 Lubrication Points and Instruction (p91)" for the repairing procedures below, and apply the specified type and amount of the grease to the specified part of the printer mechanism.
